Do Muscles Get Cut In The Zygomatic Sandwich Osteotomy?

Q: Dr. Eppley, I am interested in Zygomatic Sandwich Osteotomy. I want to know, if you need to cut through any muscles or shift their position or reattach them in this procedure? 

A: In the ZSO procedure the osteotomy cut is done just in front of the anterior tendinous attachment of the masseter muscle…so no muscles are detached or need reattached during the procedure.
